Kingdom: Phylum: Class: Clade: Order: Psittaciformes, 1830 (cockatoos) (true parrots) (New Zealand parrots) Range of parrots, all species (red) Parrots, also known as psittacines, are of the roughly 393 in 92 that make up the Psittaciformes, found in most and regions. The order is subdivided into three superfamilies: the ('true' parrots), the (cockatoos), and the (New Zealand parrots).

Parrots have a generally distribution with several species inhabiting regions in the, as well. The greatest of parrots is in and. Characteristic features of parrots include a strong, curved, an upright stance, strong legs, and clawed feet. Many parrots are vividly coloured, and some are multi-coloured. Most parrots exhibit little or no in the visual spectrum. They form the most variably sized bird order in terms of length. The most important components of most parrots' diets are seeds, nuts, fruit, buds, and other plant material.

A few species sometimes eat animals and, while the are specialised for feeding on and soft fruits. Almost all parrots nest in (or in captivity), and lay white from which hatch (helpless) young. Parrots, along with, are among the most intelligent birds, and the ability of some species to enhances their popularity as. Wild parrots for the, as well as,, and from, has diminished wild populations, with parrots being subjected to more exploitation than any other group of birds. Measures taken to conserve the habitats of some high-profile have also protected many of the less charismatic species living in the same. Heer Ranjha Full Hd Video Song Download.

Fossil dentary specimen UCMP 143274 restored as a parrot (left) or an Psittaciform diversity in South America and Australasia suggests that the may have evolved in, centred in Australasia. The scarcity of parrots in the fossil record, however, presents difficulties in confirming the hypothesis, and there is currently a higher amount of fossil remains from the northern hemisphere in the early Cenozoic.

Molecular studies suggest that parrots evolved approximately 59 (Mya) (range 66–51 Mya) in Gondwana. The three major clades of originated about 50 Mya (range 57–41 Mya). The carnivorous stem-parrot. A single 15 mm (0.6 in) fragment from a large lower ( 143274), found in deposits from the in, had been thought to be the oldest parrot fossil and is presumed to have originated from the period, which makes it about 70 million years old.

However, other studies suggest that this fossil is not from a bird, but from a (a non- with a birdlike beak), as several details of the fossil used to support its identity as a parrot are not actually exclusive to parrots, and it is dissimilar to the earliest-known unequivocal parrot fossils. Likewise, the earliest parrots did not have the specialised crushing bills of modern species. It is now generally assumed that the Psittaciformes, or their common ancestors with several related bird orders, were present somewhere in the world around the (K-Pg extinction), some 66 Mya.

If so, they probably had not their yet, but were generalised birds. The combined evidence supported the hypothesis of Psittaciformes being ', i. E., the mostly that emerged in close proximity to the K-Pg extinction. Analysis of insertions observed in the genomes of passerines and parrots, but not in the genomes of other birds, provides strong evidence that parrots are the of passerines, forming a clade, to the exclusion of the next closest group, the. Is the origin of the first undeniable parrot fossils, which date from about 50 Mya. The climate there and then was tropical, consistent with the. Initially, a named, uncovered in Denmark's and dated to 54 Mya, was assigned to the Psittaciformes; it was described from a single.

However, the rather nondescript bone is not unequivocally psittaciform, and more recently it was pointed out that it may rather belong to a newly discovered of the genus, whose fossil legs were found in the same deposits. Fossil skull of a presumed parrot relative from the Eocene in Fossils assignable to Psittaciformes (though not yet the present-day parrots) date from slightly later in the, starting around 50 Mya. Several fairly complete skeletons of parrot-like birds have been found in England and Germany. Some uncertainty remains, but on the whole it seems more likely that these are not direct ancestors of the modern parrots, but related lineages that evolved in the Northern Hemisphere and have since died out. These are probably not ' between ancestral and modern parrots, but rather psittaciform lineages that evolved parallel to true parrots and cockatoos and had their own peculiar: • • • • • • • • • • • The earliest records of modern parrots date to about 23–20 Mya. The fossil record—mainly from Europe—consists of bones clearly recognisable as belonging to parrots of modern type.
